00:30:10 Andrew Planet: Hey there! 00:30:26 Patrick Grove: https://docs.google.com/document/d/1TA-ZUay7EsWgFBSHXOQ0ZqErh_DqT2wQm4SNnCpi68M/edit?tab=t.0#heading=h.6ezgswcipqyo 00:31:12 Lorrie Irwin: Morning Patrick 00:31:24 Anna Polomska: hi all! 00:31:26 Cesare Lobascio: Ciao! 00:31:34 Patrick Grove: Hey all! 00:31:36 Chris Yuan: Hihi 00:31:51 Jane Shevtsov: Good morning from Los Angeles! 00:32:03 Andrew Planet: Enjoyed yesterday, learning to thinking differently about space ecology, think outside of the box. 00:32:07 Anna Polomska: when will the recording be available for those who missed some of the presentations? 00:33:05 Anna Polomska: thank you :) 00:33:30 Paola Castano: Thank you, Patrick! Looking forward to the recordings because I could not attend yesterday. Glad to be here and hi, everyone! 00:33:44 Patrick Grove: Welcome, glad you could make it today! 00:33:52 Luke Fountain: Hey Paola, good to see you here! 00:34:22 Paola Castano: Hi, Luke šŸ™‚ 00:41:00 Andrew Planet: Jim Lovell https://en.wikipedia.org/wiki/Jim_Lovell 00:42:18 Shantanusinh Parmar: RIP, he was my hero and inspiration. 00:43:38 Jane Shevtsov: Apollo 13 was a life support failure (caused by a power failure). 00:44:43 Andrew Planet: Apologies, clicked on raise hand by mistake 00:44:44 Irena Li: Apollo 13 is what inspired me to go into mission ops 00:46:02 Jane Shevtsov: Wow, Irena! 00:46:32 Irena Li: Life support is really the ultimate ā€œfailure is not an optionā€ 00:48:12 Irena Li: it was also the first thing they quizzed me on when interviewing at JSC 00:48:30 A. C.: Are thet using He mix atmosphere it sounded like it. 00:57:10 Jane Shevtsov: Advertise dog diving in LA and you'll never worry about money! 00:57:59 A. C.: I'll volunteer for the dog walker job. 01:27:06 Luke Fountain: Are you operating at 1 atmosphere or reduced pressure exploration atmospheres? 01:28:02 Jane Shevtsov: Next step: toilet with nutrient recovery! 01:30:33 Terry Trevino: LT. COL Lucia White!! Amazing human. 01:33:57 Jane Shevtsov: Caturday! 01:41:09 Borja Barbero Barcenilla: Looks like so much fun 01:44:20 Rob Faltersack: I wonder how shrimp would fare on a parabolic test flight before going orbital. 01:47:41 Patrick Grove: probably pretty unbothered. shrimp have been to space a handful of times, at least on Skylab and ISS. I have put them on a vibration table and they were also pretty unbothered. water buffers a lot of the shock, and it's already a bit like microgravity for organisms that experience low Reynold's numbers because viscosity is more dominant than inertia (of gravitational acceleration) 01:49:16 Andrew Planet: That's very interesting Patrick, thanks 01:54:32 Borja Barbero Barcenilla: What is the highest the plane can reach? Thinking of different radiations levels 01:55:28 Rob Faltersack: Thanks Lucia, this was fun to see. And now to come up with a good experiment to attempt. 01:57:07 Terry Trevino: I have been tracking radiation exposure at alititude, and it's very high over time and adds up to a lot over two to three years 02:02:38 David Stuart: Note that Zero-G is a commercial company and has many flights around the USA, that cost $$$. See https://www.gozerog.com/ 02:04:20 Anna Polomska: I still see the first slide ? 02:04:43 Andrew Planet: Likewise 02:05:20 Patrick Grove: thanks guys! 02:10:43 Borja Barbero Barcenilla: How similar are the genome of these strains? 02:11:34 Patrick Grove: very low PAR. does light reflected by snow still have a lot of PAR in it, I wonder? 02:12:46 Aurora Toennisson: She mentioned earlier it can get up to 2000 PAR on sunny summer days on the snow, but you might cook the algae with grow lights that strong 02:13:19 Patrick Grove: oh i missed that part, thanks. very extreme environment indeed 02:21:39 Terry Trevino: This is amazing work! 02:23:00 Lawrence Warnock: Donā€™t eat the red snow. 02:24:06 Patrick Grove: šŸ˜‹ 02:25:40 Andrew Planet: Not really a question for Q and A, just thoughts in my head. Thanks for that terminology, Carla. Hereā€™s me thinking that space ecology relative to humans is xenic, in terms of recycling waste products in a bioreactor as we contribute our own microbiome. How do we make some organisms dominant in a bioreactor if we keep adding other organisms from our own gut? 02:27:14 Rosa Santomartino: No Worries Carla. Great work!!! Very curious to see the what comes out of the clinostat experiments :) 02:27:31 Andrew Planet: Do we need some mother mass as yeast used in small scale commercial bread making, constantly added? 02:28:08 Remil Aguda: Comment: I recently finished my PhD dissertation on challenges and solutions for green micro algae cultivation in a space station. For bioregenerative life support applications, perhaps we can work on proposal on using human-derived wastewater as media. 02:30:00 Patrick Grove: @Andrew - when using bioreactors for waste recycling, there's usually several in series with different pH and temperatures that are quite extreme for the average gut microorganism, so most species are filtered out by the environment in the bioreactors. 02:30:58 Andrew Planet: Thanks Patrick 02:31:16 Andrew Planet: Wow! 03:16:18 Luke Fountain: Following Auroraā€™s question in the Q&A, could the differences in calcium (and other nutrients) in e.g. plants grown in ISS vs. Tiangong be due to different fertiliser compositions? 03:17:37 Luke Fountain: Has there been any consideration of nitrogen? Nitrate accumulation could also cause concerns for crew health - a particular issue in salad crops 03:23:28 Luke Fountain: Iā€™ll touch on this further in my talk 03:25:52 Kevin Chaz Shaffman: What would the advantage of a low oxalate spinach be to normal spinach? 03:26:01 Luke Fountain: A large variety of crops are currently being tested at KSC for nutritional content as well as yield - there may be some answers there. Good suggestions, Jane! 03:26:34 Jane Shevtsov: Oxalate contributes to kidney stones. 03:27:42 Terry Trevino: We are releasing all our data by October. 1800 plants two years, uptake and mineral analysis included in Ultra High CO2 environment 03:28:25 Terry Trevino: Trent Smith helped me a lot 03:29:23 Kevin Chaz Shaffman: Is CaOxalate really insoluble or something vs other ca-organic acids? 03:34:05 Rachel Rivero: Thank you to everyone for the great comments and suggestions! This is very helpful and interesting to consider how it could be incorporated. Luke, Iā€™m excited to see the results of the nutritional content from KSC! Do you have any idea of when it may come out? 03:34:12 Aurora Toennisson: Space BLT 03:36:08 Luke Fountain: Thanks Rachel, Iā€™m not sure of a specific timeline but the work is currently being undertaken by our team, I would expect within the next year or so! 03:36:36 Rachel Rivero: Cool! Thank you for letting me know. šŸ™‚ 03:37:10 Luke Fountain: No problem! 03:44:05 Jane Shevtsov: There's a Biosphere 2 cookbook, "Eating In". 03:46:32 Kai Staats: Actually, they grew 100% of their food. Their plant yield was limited by reduced sunlight due to an El NiƱo year and the space frame of the structure, and pests that had to be hand-removed, as they had no pesticides and no herbicides (for good reason). The total yield was just 25% of an optimal output for the same plants in ideal conditions. Nothing to do with being farmers, but the limitations of the conditions. Many lessons learned. The second mission (1994) made significant changes and saw far higher yield. 03:54:27 Kai Staats: A great overview and really cool experiments of your own hands and effort. 03:55:34 Rob Faltersack: @James, Thanks for the share! Hear hear for citizen science! Would you consider sharing your build, BOM, pricing to appropedia.org? 03:57:23 Luke Fountain: Menu fatigue is a very real concern, thanks for pointing it out James! 03:59:07 Luke Fountain: Itā€™s an interesting problem with lots of factors involved, but food has to be palatable for astronauts to eat it! 03:59:07 Jane Shevtsov: I want to organize a space food festival! 04:01:08 Patrick Grove: mmm astronaut icecream šŸ˜‹ 04:24:44 Jane Shevtsov: Let's think about what this means for waste treatment. 04:25:59 Andrew Planet: Thanks Lukeā€”made me go off at a tangent and consider if non-photosynthetic myco-heterotrophic plants (plants that parasitize fungi) could be engineered to be edible, especially in relation to mycorrhizal fungi. 04:26:19 Aurora Toennisson: In hydroponic systems that are aerated, how much nitrification occurs over time? Is that a concern for flight hydroponic systems that aim to favor ammonium? 04:27:22 Aurora Toennisson: Second unrelated question, do you see more rapid pH changes in eCO2 compared to ambient due to changes in nitrate uptake? 04:29:56 Terry Trevino: net positive 04:30:11 Terry Trevino: Agreed!! 04:30:28 Terry Trevino: Good point 04:32:09 Aurora Toennisson: Wow! I eagerly await your next ASGSR talk on eCO2 and pH! 04:33:23 Terry Trevino: Amazing Luke!! 04:35:13 Terry Trevino: Confirmed Patrick, Net positive charge is "severely" impacted to regolith, and might flip 04:35:29 Patrick Grove: good to know! i never hear anyone talking about that! 04:35:58 Cesare Lobascio: Dinner time!!! 04:36:15 Borja Barbero Barcenilla: Great talk Luke! 05:30:51 Lorrie Irwin: Freida whats your email? 05:31:26 Patrick Grove: taub@uw.edu 05:35:28 Lorrie Irwin: Thanks Patrick 05:51:44 Shantanusinh Parmar: https://ngs.simoc.space/ 05:56:22 Terry Trevino: Excellent work, Kai. 05:56:49 Harrison Coker: Incredible presentation! šŸ˜Ž Thank you 05:57:05 Marshall Porterfield: https://www.pnas.org/doi/10.1073/pnas.1711842115 05:57:41 Andrew Planet: Inspiring words and yes many of our species are not at all self-aware. 05:57:49 Marshall Porterfield: https://www.pnas.org/doi/10.1073/pnas.2204892120 05:58:55 Marshall Porterfield: https://www.nature.com/articles/s41586-020-3010-5 06:03:46 Rob Faltersack: User facility model is also working well for other university plant research labs, and also for analog astronaut studies. 06:05:18 nathan O'Neil: very cool! 06:05:25 Patrick Grove: Any additional questions for Kai? 06:05:28 Rachel Rivero: https://github.com/overthesun/simoc 06:05:56 Kai Staats: https://simoc.space 06:06:27 Rob Faltersack: Compost tea especially from vermiculture is gold. 06:07:01 Lorrie Irwin: I can verify its aerobic 06:07:07 Shantanusinh Parmar: Also for a web demo, https://ngs.simoc.space/ 06:08:01 Lorrie Irwin: thanks Kai 06:15:32 wfdempster@aol.com: Thanks and good to see you all. Bill 06:22:21 Rob Faltersack: @Fisk, you could also check into HTM or hierarchical temporal memory, which proposes to reveal causation in any time series structured dataā€¦.if you are curious. 06:39:45 Jane Shevtsov: Where would perchlorate fit? 06:46:25 Harrison Coker: Your biomining boxes are incredible. Awesome talk Colin really enjoyed 06:47:34 Patrick Grove: yeah those boxes with all the precipitated minerals are crazy! 06:47:45 Borja Barbero Barcenilla: Great job Colin!! 06:48:09 Borja Barbero Barcenilla: Moon Village Association group very well represented! 06:48:35 Jane Shevtsov: Very cool stuff, Colin and Briar! What parameters are you using to control your systems? And what kind of achine learning does Gaia OS use? 06:48:46 Patrick Grove: šŸŒ•šŸ™ļø 06:50:20 briar Fisk: @Faltersack, thank you for the lead. It sounds similar to what we use, based on the terms you used there anyway, our system is hierarchical, sparse, and handles temporal data to reveal causal chains and exploit them. 06:55:58 briar Fisk: @Jane Thank you! The suite we are setting up right now, if that is what you mean by parameters, contains flow rate, pH, temperature, and total dissolved solids. As for the machine learning I am using an architecture called Semiotic-Neural networks, my pet project going back to 2013 so not much published on it. I would love to discuss it at way more depth than you'd ever want if you'd like more information on them. My email is briarfisk@gmail.com for you, or anyone, who wants more info on the ML / GaiaOS. 06:56:58 Borja Barbero Barcenilla: Yes. Those heavy metals need to be dealt with 07:01:46 briar Fisk: If the pH needs to raise then the system will find previously encoded instances where the pH rose, it will then select from that the actuator outputs which were associated with the rise in pH. Then it outputs those signals to the efferent output array, which is then picked up and delivered to the actuator by the driver program. Unless you mean what needs to change if you desire a higher pH than you previously had the goal set at. In which case you change the pH goal value to the new one and that is it. It will dynamically pursue the goal value like a thermostat with no changes needed by the user beyond setting the new value. 07:03:29 Rachel Rivero: Is it possible you need a different amendment for germination vs growth (transfer plants)? You said it increased germination but not height/weight. 07:03:56 Harrison Coker: https://soilhealthinstitute.org/our-work/initiatives/slakes/ 07:04:16 Jane Shevtsov: @briar I'm asking what the compiter system can/will be able to actually manipulate, 07:05:55 Rachel Rivero: It would be cool if a lot of these apps had open source code. They are really cool to ā€œdiagnoseā€ plant phenotypes but canā€™t be implemented into larger systems. 07:06:12 Patrick Grove: true! 07:06:58 Harrison Coker: MGS-1 always kills our plants and no one knows why lol. The differences between batches are pretty extreme too 07:07:01 briar Fisk: That is true yes @Patrick thank you. That is the active step right now, I am building the unit to ship to Colin. Titration is planned I know, but the specifics are beyond me for the chemistry. @Jane, oh oh, it will manipulate whatever you plug into it. The GaiaOS only sees raw values, an agnostic interface, so it is designed to be general purpose plug-n-play. With Colin's systems it will contorl the valves, pumps for flow-rate control, mechanism for cleanout, all the controls Colin decides it needs. When you plug a sensor, or actuator, into it you register it with the system as a sensor or actuator. 07:07:59 Rob Faltersack: Thanks Rachel, that gives me a gap to fill. Iā€™ll see what can be gleaned from the data collected by OpenAg computer vision related to diagnosis or categorization of phenotype. 07:08:34 Jane Shevtsov: Thanks, Harrison and Briar! 07:08:45 Rachel Rivero: That would be amazing, Rob!! 07:09:14 briar Fisk: You're welcome Jane, thank you for the questions! 07:10:26 Colin Lennox: here here, the questions guide the science :). ty! 07:11:45 Andrew Planet: Thanks Aenghus, made me delve into endoliths to see if regolith can be broken down first to transform before growing plants in it. 07:11:46 Kevin Chaz Shaffman: Some asteroids do have a regolith on their surface, its super cool 07:12:29 Terry Trevino: Now called Space Resources. Exolith has changed their name 07:13:14 Harrison Coker: Great work Aenghus! šŸ™‚ 07:13:57 Jane Shevtsov: https://docs.google.com/document/d/1dbPRTfiBiq66MiJtxifwFkzX52eEYJ4U/edit?usp=sharing&ouid=109678189789435119043&rtpof=true&sd=true 07:14:09 A. C.: Thanks. 07:14:25 Rob Faltersack: Thanks Jane! 07:26:13 Kai Staats: Danica!!! I just showed your beautiful Mars yard in my talk! 07:32:44 Borja Barbero Barcenilla: Congratulations!!! 07:35:31 Borja Barbero Barcenilla: What a cool background Danica!!! 07:35:44 Rachel Rivero: Wow! So cool! 07:37:10 Danica Vallone: Thanks, guys! Ask allllllllll the questions!! 07:43:38 Kai Staats: No!!! That was where I got my first funding for SIMOC! It was born at ASU Interplanetary Institute. So sad! 07:47:24 Jane Shevtsov: I've been looking for data science jobs. At least 50% are advertising. 07:49:54 A. C.: It is! 07:50:20 Rob Faltersack: I also worked as a developer in advertising for Ƙrsted, Loreal, Nestle, there is something to be learned from every experience. Very fast paced. Now Iā€™m in biomedicalā€¦slow AF but well funded. 07:50:42 Danica Vallone: I feel you... on both fronts! 07:51:10 Rob Faltersack: @Jeff, I like the mention of ā€œsell the deliverableā€ not the effort 07:57:53 A. C.: Sounds crazy but should grant application initiatives be developed to go to some of the other wealthy nations, Saudi Arabia,, Qatar, UAE ? 08:07:09 Borja Barbero Barcenilla: Feels to me that money is being spent to send humans to moon and mars. However it feels like we still not know how to live sustainably for multiple yearsā€¦ 08:07:24 Patrick Grove: šŸ’Æ 08:08:25 briar Fisk: The Moon Society's workshop came to the conclusion that the boomtown model is the most likely way to get colonists on the moon, adjacent to mining and industry in space rather than direct colonization effots. I am curious if things are far enough along to work with mining companies/other industries towards space industry to get funding from them? Or is that not a realistic option being far out on the horizon to where they won't see it as a viable investement yet? Framed as creating the tech that allows their mining rigs to get out there and get those sweet sweet space rocks? 08:08:47 Patrick Grove: 1. Advanced Exploration Systems 2. Mars Technology 3. Commercial Moon to Mars Infrastructure and Transportation Program ^ Jeff Smith recommends we look for funds here! 08:09:36 Danica Vallone: Also DoD 08:09:43 Kai Staats: I do not believe that ā€œsustainableā€ is simply not an important function of the first missions to Mars. They will more simply bring all food and initial water supply (to be recycled as on ISS). Sustainable systems will be a long-term consideration, literally decades or a century from now. Thatā€™s my two bits. 08:09:44 Borja Barbero Barcenilla: šŸ’ø 08:12:05 Borja Barbero Barcenilla: Thanks for your answer Kai. Seems like we could spend that money knowing how to get those first missions done in a fashion that could be ā€œsustainableā€, or we could spend the money in bringing everything they need in making a bigger rocket and more fuel. 08:12:40 Borja Barbero Barcenilla: I love colossal 08:12:52 Rachel Rivero: Me too!!! 08:12:54 briar Fisk: @Zaheer My email is briarfisk@gmail.com if you'd like to talk sometime. The Moon Society crowd has some good ideas on this one, one focus of the workshop was on using the vacuum and other environmental factors on the moon to produce things that are difficult here, vacuum is expensive on earth but "free" on the moon. 08:13:30 Borja Barbero Barcenilla: 100%. Great communication folks at Colossal 08:13:55 Borja Barbero Barcenilla: And scientist too that are leaving or not getting a job at NASAā€¦ 08:14:01 Kai Staats: Agreed, but I fear that simplest solution, meaning the one that can be done with the least effort (freeze-dried food) will win, in the first missions. And to be honest, if I were an astronaut, Iā€™d want to know that I have 2 years of food in packages, food that will be there no matter what, than to risk a crop failure a long, long way from home. We have to establish a foundation then build toward sustainability with fall-backs and safety systems in place. 08:15:17 Borja Barbero Barcenilla: Yes I would say the same if I were an astronaut Kai. My wife does not let me go though 08:15:27 Kai Staats: šŸ™‚ 08:17:07 Borja Barbero Barcenilla: I love the enthusiasm of all the panelists!! 08:17:18 Borja Barbero Barcenilla: Patrick next year we need 2 hours of this 08:17:25 Patrick Grove: i totally agree 08:17:27 Rob Faltersack: Space Ecology brought to you raw and uncut! 08:17:34 Borja Barbero Barcenilla: šŸ˜‚ 08:17:35 Rachel Rivero: Love it! 08:17:40 briar Fisk: Agreed, not near enough time! 08:17:45 Irena Li: šŸ‘ 08:19:20 Borja Barbero Barcenilla: Amazing job on the symposium. Many congratulations to all the organizers 08:20:27 Terry Trevino: I want to see fisticuffs 08:21:08 Terry Trevino: Beautiful advice 08:21:25 Kai Staats: A network is always stronger than a solo endeavor. 08:21:49 A. C.: Lets get funding for bio weapons to the upcoming invasion force from Zeta Reticuli. LOL. 08:22:08 Christina Johnson: If there are young people in your life, make sure you pass on whatever knowledge you can, in fun ways. Help them to build their skills. Joyfully. because people learn faster and won't burn out as fast if they are having fun. 08:22:50 Terry Trevino: Love that, Kai and Christina 08:23:18 Kai Staats: Exactly. More than one skill. Be ready to switch lanes. 08:23:30 Cesare Lobascio: great panel! 08:23:47 Terry Trevino: See ya again next year. 08:23:48 Rob Faltersack: Excellent advice from all! 08:23:48 Cesare Lobascio: great Symp! 08:23:56 Kai Staats: This is m favorite workshop / conference this year. 08:23:59 Kai Staats: NO!!!! 08:24:00 Sharon Doty: Thank you for organizing this excellent workshop! 08:24:08 briar Fisk: Awesome event, glad to see it grow! 08:24:23 Marshall Porterfield: porter@purdue.edu 08:24:54 Paola Castano: Thank you for another great workshop. This last conversation was very important and timely for this community. Greetings, everyone! 08:25:01 A. C.: Lets have SEW bi annualy. Need this in another 6 mo. Excellent. 08:25:02 Rachel Rivero: Thank you so much!! 08:25:22 Lorrie Irwin: Thank you all ! 08:25:31 briar Fisk: Aye! Good job Patrick! 08:25:35 oscar monje: great job Patrick 08:25:42 Rob Faltersack: Hell yeah! 08:26:00 Luke Fountain: Great job Patrick and thanks for another great workshop, itā€™s a highlight of the year for sure! 08:26:13 Cesare Lobascio: ciao ciao ciao buona notte! 08:26:16 Tarun Bandemegala: Thank you very much everyone! This was great
